Huawei Account Kit not working, how to implement?

trying to implement Account Kit into our app and it is not working.

Using com.huawei.hms:hwid:5.0.3.301 and on signin, blank activity is shown. Hitting back button from this blank activity, log would show onActivityResult 1002 0.

Tried building the demo project from https://github.com/HMS-Core/huawei-account-demo. It is the same thing, clicking on login nothing shows, clicking back button would show signin failed.

What could be the issue?

#UPDATE:
ags file was missing from demo, hence the blank activity. Adding the AGS file fixed it.

After verifying that the native android SDK build does work on my device, continued trying to implement on Unity.

Downloaded 4.0.4.300 AccountSDK with 4.0.4.301 Core. Ran the APK and the following error occured:

     Caused by: android.content.ActivityNotFoundException: Unable to find explicit activity class {com.test.test.huawei/com.huawei.hms.activity.BridgeActivity}; have you declared this activity in your AndroidManifest.xml?

        at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:1374) 

So then I copied the bridge activity from the HMSSdkUI's manifest into my manifest and the the app built:

        <activity
            android:name="com.huawei.hms.activity.BridgeActivity"
            android:configChanges="orientation|locale|layoutDirection|fontScale|screenSize|smallestScreenSize|screenLayout"
            android:excludeFromRecents="true"
            android:exported="false"
            android:hardwareAccelerated="true"
            android:screenOrientation="behind"
            android:theme="@android:style/Theme.Translucent" >
            <meta-data
                android:name="hwc-theme"
                android:value="androidhwext:style/Theme.Emui.Translucent" />
        </activity>

However, requesting sign in still results in blank activity. Here is the log: I am suspecting it has to do with the BridgeActivity??

Error code 10020 means invalid parameters.
Can you check if you are adding correct parameter.
Refer Huawei official document on how to sign in using huawei id.

Are you using HMS Analytics kit because 10020 code is the error code of analytics kit. Check out error codes of analytics kit:

In the demo, if you click signin, app will try to get authorization to your Huawei Account. Please check whether you are running on the HMS phone and Huawei account is log in.

The demo in the github is a little old, you can download the code from the official page directly. The github demo will be updated ASAP.

Update:

1. Please modify the xxx.jks info in the build.gradle file in the app directory.
2. Please create a project on the AGC platform and set the SHA256 information in the xxx.jks file on the AGC platform.
3. Please download the agconnect-services.json file from the AGC platform and place the file in the app directory of the project.
